A shield produces a 'dazzling' effect: disorientation and temporary and fully reversible blindness in subjects for the purpose of threat deterrence. The apparatus is comprised of a plurality of light emitting diodes (LEDs) capable of intense illumination. Light emitted by each LED is further pulsed and focused by reflective optics to produce a dazzling effect. The shield further provides ballistic protection, chemical or electrical crowd control functionality, safety-glass breaking capability, optically propagated communications and an arm strap to further secure the shield.

LED dazzler shield

An apparatus produces a 'dazzling' effect: disorientation and temporary and fully reversible blindness in subjects for the purpose of threat deterrence in both civilian law enforcement and military engagements without the use of lasers. A plurality of light emitting diodes (LEDs) capable of intense illumination is provided. Light emitted by each LED is pulsed and focused by reflective optics to produce a pulsed beam of sufficient intensity that the combined effect of the beams from the LEDs induces dazzling in subject viewers in the target range. Further included in or ancillary to the invention are a power source for powering the LEDs a signal source and controller for controlling their illumination and pulsing, and a shield suitable for protecting a user against projectiles.

Nonintrusive sensors capable of measuring various storage cell parameters such as voltage, state-of-charge, electrolyte level, internal resistance, and temperature are attached to a monitoring module which gathers and processes signals representative of information concerning the condition of electrolytic storage cells and transmits the information to a central computer for further processing. In response to commands issued by the central computer, appropriate maintenance and/or repair operations can be initiated. Alternatively, the system described can be used to automatically perform such maintenance tasks as checking and adding electrolyte levels, reducing the voltage in cells whose output voltage is too high, and leveling the state-of-charge of each cell in an array of electrolytic storage cells. The system can monitor other functions of the electrolytic storage cells, including the evolution of hydrogen gas and the accumulation of sediments in individual electrolytic storage cells.

A DC to DC converter capable of operating from a power source whose output voltage may change over a 10 to 1 range. A switching modulator is used to convert the DC input voltage into a pulsed voltage. Feed forward control techniques are used to control a switching modulator to rapidly compensate for changes in the amplitude of the input voltage. Feed back techniques are used to maintain the output voltage at the desired value. Isolation between the input and output is provided using a transformer to couple the switching circuits to a rectifier and filter which produces the output voltage. A filter optic link provides isolation for the feed back signal.
